Abstract：
A concept of the quasi-composite system in the process of the pre-equilibrium emission is presented in this paper. On the basis of the principle of detailed balance, the existence of the factor, [γ_βω(π_β, 0,ν_β, 0, E—U)/g_π,ν, has been proved with an account of the distinguishability between protons and neutrons. A formula for the rate of the complex particle emission in the pre-equilibrium process there by can be obtained. The theoretical calculation results fit the experimental data quite well, especially in the high energy part of the energy spectrum the agreement are much better than ever before.
